Israel said its Iron Dome missile defense has proved its mettle in recent days, in a conflict that has become the biggest test of an air-defense system in which the U.S. has invested more than $200 million.

The Israeli military said Friday that it would accelerate the deployment of a fifth Iron Dome battery to bolster defenses in southern Israel, saying the system forms an effective shield against rocket salvos from Gaza.
